I think you have a misconception on how your OS works. Most likely your two user accounts have different uids and different main groups. Your data folder most likly is owned by user1:group1 with rxw------ permissions, so user2:group2 cannot read nor write to that directory.
We already know from https://mail.trinitydesktop.org/mailman3/hyperkitty/list/users@trinitydesktop.org/message/JRQNYMOUW5PC5RXJXAZ3245OLVAZV2XR/ for user1 = chris = 1000:1000 drwxr-x--- for user2 = chrisontde = 1001:1001 drwxr-x---
You might want to check these and post the result: # groups user1 # groups user2 # ls -ld data_directory
